Lemon balm is a member of the mint family, which includes citronella, pennyroyal, peppermint, and spearmint (although spearmint doesn’t contain menthol). It is a fragrant herb grown easily in temparate climates.

Parts Used: Leaves (infused or crushed) and their essential oil.

Attributes: Contains menthol, volatile oils, antioxidants, flavonoids, and tannins. The mints are antiviral, antibacterial, and antiseptic.

Uses: Lemon balm can be used as a substitute for lemon oil for furniture polish, and mints in general freshen the air. Mints are excellent pest repellents–pennyroyal and citronella are famous examples–and especially repel mice, mosquitoes, and fleas.

Where to Find: Available in health food stores and from herb suppliers.

Caution: Pregnant women should not use pennyroyal. The essential oil of pennyroyal is highly toxic and should not be taken internally.
